How do I allow smoothing in externally loaded images?

In Flash, I can go into the properties of an image in the library and check 'allow smoothing' to enable resampling when the image is scaled or rotated.

How can I achieve the same effect for images loaded dynamically by the 开发者_运维百科SWF from an external URL?

For AS2

take a look here: http://www.giordanopiazza.com/blog/flash/allow-smoothing-for-external-images-as2/

For AS3

set bitmap.smoothing = true;

Seems there is no simple answer:

At this link http://www.actionscript.org/forums/showthread.php3?t=89255 some guy called Flash Gordon posted quite good class for it, so you have to play with it probably.
